ELECTRIC-LAMB BRACKET I Application filed June 4, 1929: Serial No. 368,309.

This invention relates to improvements in electric lamp bracketsor supports for inclustrial purposes. More particularly this invention relates to a generally improved lamp bracket for supporting one or more electric lamps for use on serving machines and like machinery where it is necessary that the lamp or lamps be supported close to the work, yet in a position which does not interfere there 19 with, and whereby the lamps may be quickly adjusted for the purpose of efiicient illumination.

The object'of the invention is therefore to i provide a lamp bracket adapted to support one or more standard electric lamps in a manner to provide rigid support, extreme adjustability and so arranged that the lamp cord does not become tangled withthe bracket or unduly twisted no matter how the lamps are '20 adjusted. Y

The invention is embodied in a lamp bracket having a clamping ring base support and above the latter there is provided interconnected brackets or supporting. members per- 25. mitting the lamp carried thereby to be adjusted practical universally in all directions with respect to the main supporting member. p a

The invention is illustrated in the accompanying drawing in elevation, partly perspec tive and with parts broken away.

Referring to the accompanying drawing, the reference numeral 1 denotes a main support in the form of a ring adapted to be firmly clamped to the frame of a sewing machine, for instance, by means of a bolt and nut as at 2. The dotted line 3 inside the ring represents the member to which the ring is clamped.

The ring 1 carries at the top a leg member comprising two substantially symmetrical pieces 5 and 6 which are pivoted together at 7. The lower piece 5 is pivoted to the ring at 8. The axis of the pivot 8 being at right angles to the axis of the ring and theaxis of the pivot 7. i

The upper leg piece 6 sup orts two symmetrical U-shaped lamp socket supports 9 and 10 which are pivoted to each other at the co-axial pivots 11 and 12, the pivot 12 also 50 serving to pivot the two supports to the leg piece 6. At the pivot 11 the U-shaped sup-. ports carry a plug bracket 13 which carries a standard push plug socket 141 adapted to receive the prongs of a standard push plug 15 at the end of the supply cable 16.

The drawing shows the one U-shaped support 10 moved-on the pivotsll and 12 out of alinement with the other support 9. Each support carries a nipple 17 to which is secured a standard electric lamp switch socket 18, 19. 20 indicates the lamps, parts of I which are broken away.

The pivots which serve to connect the several parts may be of any usual friction type, or as shown at 7 and 11 wing bolts may be used for clamping adjacent parts in fixed adjusted position.

Each U-support 9 and 10 has a hole 21;permitting passage of the wire cables 22 22 from the socket 14 to the lamp sockets 18 and-19.

. From the drawing and the foregoing description it will be seen that the entire bracket is adjustable horizontally on the pivot 8, and the lamps are individually adjustable horizontally on the pivots 11 and'12.

The entire upper structure is adjustable vertically on the pivot 7 and the socket support 13, by reason of the pivot 11, is free to adjust itself and the socket 1 1 with respect to the cable 16 to allow for twists in the latter. I

Again, by reason of the manner in which the cables 22 are mounted through the U- supports, each lamp may be adjusted horizontally without fear of pulling and twisting the cables.

The several parts of thedevice are duplicates and the entire structure may therefore be made at very little cost and at the same time Very substantial to permit adjustments and long use.

lVhile the invention is disclosed in its preferred form, nevertheless I wish it understood that I reserve the right to make such alterations and changes therein as fall within the scope of the appended claims.

I claim:

1. A lamp bracket comprising a main clamping ring, two pivotally connected op-' posed horizontally disposed symmetrical U-- shaped lamp socket supports, means for supporting the latter on'said ring to permit horizontal and Vertical adjustment of said supports with respect to the ring, a push plug socket carried by said supports in rotatable. relation thereto, means for supporting lamp sockets on said support and cables passing from said lamp sockets to the said push plug socket in fixed relation to the said supports.
